Siri is expected to take center stage at the event, with upgrades across iOS, Mac OS, Watch OS and tvOS. Minor hardware updates may also be revealed, though Apple tends to save the biggest hardware announcements, such as the coming iPhone 7, for its blockbuster event in September.

Good morning from San Francisco.

Welcome to the MarketWatch liveblog of Apple WWDC.

Stock is down about 1% but is up about 17% quarter-to-date. Apple announced that it will be livestreaming Monday's keynote, which some Apple-watchers say suggests the company was planning to announce "something big."

Apple announced last week that it will live stream keynotes at this week’s Worldwide Developer Conference, which triggered quite a stir among Apple watchers.

Why?

Because an Apple livestream suggests the tech power house is planning to unveil something big.

“Yeah, it\’s a big deal all over again,” analyst Roger Kay of Endpoint Technologies Associates told MarketWatch. “Livestreaming will bring in a larger audience for the breathtaking reveal. Heretofore, only attendees got that level of access.”

If Apple is trying to pump up the volume ahead of next week\’s World Wide Developer Conference, then it could be \”mission accomplished\” for its Internet software and services chief, Eduardo \”Eddy\” Cue.

Apple\’s long-time design chief Jony Ive will have a much bigger role in this year\’s Worldwide Developers Conference, though it remains a mystery whether the notoriously shy Brit will actually take the stage at Monday morning\’s keynote.
